弹射类火工装置需要测量其出口速度,但由于火工装置的动态冲击特性常难以获得稳定可靠的数据。文中介绍了一种光电测速系统,它具有非接触测量、动态响应好等优点。经过试验验证可以用于火工装置的测试。
Ejector-like fire units need to measure their exit velocity, but stable and reliable data are often difficult to obtain due to the dynamic impact characteristics of the fire unit. This paper introduces a photoelectric velocity measurement system, which has the advantages of non-contact measurement, good dynamic response. After the test can be used to test fire apparatus.
